You are way ahead of me now. LOL.


Is it possible that it's an older unit and maybe not efficient? How much of
your water is pumped through the system on a regular basis? I was thinking
with a really efficient solar array, I could heat the house most of the day
with a system like this. You seem to be saying that won't be so?

Hmm, I wonder if a car radiator would be cheaper and just as effective?


What temp does the water get down to after dark? I assume, after dark, you
are cycling the water only through the radiator and not the array as well?

  Seems like it would be BTU in = BTU out - losses.
If you have 2000 pounds of water raised 50F that would
be 100,000 BTU. Hard to imagine that you would use
that much heat in just one hour.

After searching "solar thermal"+"forced air" I came up with:

Look down the page at Air Hanglers.

A friend told me about a device he saw that allows a solar hot water system
to be used to heat the air in a forced hot air system, like a heat pump. I
can't google anything up. Can someone provide me with a keyword or two?
maybe a URL to a product?

This is exactly what I am talking about. Now to find a source to research
pricing...
